This essay seeks to determine the primary factors influencing the fall of the Kuomintang Regime in China and the impact of United States policy on the final outcome of the Chinese Revolution. In compiling the essay, a search was made of the available literature and a historical review/overview was completed in order to provide a structural framework. Using this structural framework as a continuous reference and a point of departure, the most popular theories on the failure of the Kuomintang Regime are reviewed from the point of view of their proponent. Each theory is then analyzed in light of the literature available. Although many factors such as nationalism, World War II, and the military balance impacted on the situation in China in varying degrees, the primary cause of the Kuomintang failure in China was its social and economic policies. The situation was compounded and accelerated by the chaos and corruption within the regime itself. United States policy appears to have had no appreciable impact on the outcome of the Chinese Revolution.
